Ciclos gametocénicos continuos y discontinuos en anuros neotropicales

Abstract

Se hace un análisis de las características endócrino-ambientales del ciclo sexual, especialmente masculino, en Anuros de Sudamérica. Prevalecen ciclos continuos, con relativa mente leves variaciones estacionales, pero ciclos discontinuos se verifican con carácter de autoregulación, a la vez en ambientes sub-antárticos, fríos, y en ambientes, tropicales o subtropicales cálidos.

A comparative analysis is carried out dealing with the endocrinous and environmental relationships of the male sexcycles of South-American Anurans. Continuous cycles are prevailing, and a very small seasonal variation is pointed out. Moreover discontinuous probably self-regulating cycles have been founded both in the sub-antarctic cold environments and the tropical or subtropical districts.
